Assembly: mscorlib.Extensions (in mscorlib.Extensions.dll)
An exchange key is an asymmetric key pair used to encrypt session keys so that they can be safely stored and exchanged with other users. The Exchange value specifies an exchange key. This value corresponds to the AT_KEYEXCHANGE value used in the unmanaged Microsoft Cryptographic API (CAPI).
A signature key is an asymmetric key pair used for authenticating (digitally signed) messages or files. The Signature value specifies a signature key. This value corresponds to the AT_SIGNATURE value used in CAPI.
